This paper models a warm standby system where a single element is online performing a
specified mission task (eg, a computing task) and subject to corrective replacement (CR) by …

Decisive applications, such as control systems and aerial navigation, require a standby
system to meet stringent safety, availability, and reliability. The paper evaluates the …

Warm standby is an energy-saving redundancy technique that consumes less energy than a
conventional hot standby method. It can be naturally integrated with an energy storage …

In this paper, we consider a two-unit, non-identical cold standby system under general repair
with or without priority. In the prioritized case, one unit in the system is designated to serve …

Optimal component order can effectively improve the system reliability for the design of a
warm standby sparing (WSP) system. The optimal component order in the 1-out-of-n WSP …

The mixed redundancy strategy is a recently introduced powerful redundancy technique for
improving system reliability. So far, the performance of the mixed redundancy strategy is just …

This paper considers a new type of optimization problems, the optimal standby mode
selection problem in 1-out-of-N: G warm standby systems where multiple standby mode …

This paper investigates the heterogeneity of components with proportional hazard rates in a
redundant system. The total number of those standbys surviving the failure time of some …

The paper considers heterogeneous 1-out-of-N warm standby systems when all
components can experience internal failures whereas operating components are exposed to …

Redundancy techniques have been extensively utilized to enhance the reliability of
engineering systems. There are three different types of standby techniques, cold, hot, and …
